Answer:
Step-by-step explanation:
Subtract
6 u from 2 u .
− 4 u + 9 = 19
Move all terms not containing u to the right side of the equation.
− 4 u = 10
Divide each term by − 4 and simplify.
u = − [tex]\frac{5}{2}[/tex]
The result can be shown in multiple forms.
Exact Form:
u = − [tex]\frac{5}{2}[/tex]
Decimal Form:
u =− 2.5
Mixed Number Form:
u = − 2 [tex]\frac{1}{2}[/tex]
